In "Sensible Plumbing," FHB #216, master plumber Dave Yates addresses whole-house plumbing design. A more advanced plumbing technique is the integration of a hot water recirculation system. A recirculation system is designed to make hot water available at the tap nearly instantly.

There are two main components to an effective hot water recirculating system: the recirculating pump installed on the hot water discharge line of your home's water heater, and the sensor valve installed on the supply lines of a faucet at the farthest distance from the water heater.

For the greatest efficiency in pump-driven hot water recirculation, one must be willing to give up on the dream of instant hot water and settle for waiting a few seconds using an on-demand system. On-demand systems rely on the user to activate the pump at the fixture when hot water is needed.

Any recirculating water system is going to make your water heater run more frequently, but because there is a bigger supply of water at a higher temperature the water heater will not likely run as long—even if it runs a little more frequently. How efficient the system will be depends on water costs, energy costs, the type of water heater and ...

HOT WATER HEATING SYSTEM BASICS AND DIAGRAM. Hot water heating systems (Figure below) transport heat by circulating heated water to a designated area. Heat is released from the water as it flows through the heating unit (coil, terminal). After heat is released, the water returns to the boiler to be reheated and recirculated.

The Smart Recirculation Control controller is designed to sense when hot water is drawn from any plumbing fixture and to run the recirculation pump until the water in the recirculation loop is hot. The microprocessor-based design monitors the temperature of the water in the loop using a unique dual temperature sensor design to ensure the water ...

If you are tired of waiting for hot water or don't like the idea of wasting water, consider installing a hot water recirculating system or having one installed. The principle of these systems is simple: A recirculating pump installed in the plumbing lines creates a loop that slowly and constantly circulates the water in the hot water pipes back into the water heater for reheating.

Hot-water circulation loops use a small pump to circulate hot water between a water heater and a distant bathroom or kitchen. Creating the loop is fairly easy; however, doing so in a way that doesn't waste a lot of energy is a little trickier. Learn how to efficiently reduce your wait time for hot water.

Hot water recirculation pumps

Hence, in a recirculating system, the hot water being pumped through the piping always tends to have a higher pressure than the return line to which it connects. If the recirculation system connects to the cold water supply to the water heater, the water can reverse course and go into the cold water supply.
